.'Z'o a/ZZ whom it may concern.-

Be it known that I, FRANCIS M. Sworn, of the city of Seymour, Jacksoncounty, and State of Indiana, have made a new and useful Improvement inScythe-Snath Fastenings, of which the following is a full, clear, andeX- act description, reference being had to the annexed drawings, makinga part of this speci ication, in which- Y Figure l is a face view of theimproved fastening; Fig. 2, a side View; and Figs.' 3 and 4, views inperspective of the fastening-plate and fastening-bolt respectively. e

The same letters of reference denote the same parts.

This invention is an improvement in that class of fastenings whereinprovision is made for adjusting the blade to the desired inclinationwith the snath by means of aplate which engages with the blade-shank,and is adapted to be swung upon and clamped to the snath.

The improvement consists in the special mode of constructing theswinging plate and clamp and combining them with the blade and eachother.

A represents the lower end of an ordinary scythe-snath- The collar B isattached to the snath, and the scythe-blade C is secured by means of theeyebolt D, whose eye encircles the blade-shank c, and whose stem passesthrough the collar and snath, and is fastened thereto, all in the usualmanner. In place of notching the adjusting-plate E at its edge to engagewith a pinion upon the clamping-bolt, and pivoting the plate at itslower end to the snath at a point beneath the bladeshank, the plate ispivoted at its upper' end, e, to the snath, and the socket e', toreceive the toe c of (No model.)

the blade-shank, is at the lower end of the plate, and between its ends,at e2, the plate is 4o slotted to receive the clamping-bolt F. At oneedge ofthe slot, and in the face e3 of the plate, is a series ofdepressions, e4 c". The bolt F is provided witha lateral proj ection, f,having one, and preferably two teeth,f f', whieha 5 are adapted toengage in the depress-ion e4 et. These teeth, however, are not radial tothe center ofthe bolt-stem f2, but to the pivote. The scythe-blade isfirst set to the desired angle with the ysnath andthen fastened bytighten- 5o ing the clamping-bolt. This draws the teeth ff into thedepression e4 e, and as long as they remain thereinthe plate and bladeare securely locked,for owing to the direction in which the teeth f fare extended-that is, radially to the plate-pivot, and not to thebolt-stem-the bolt cannot be rotated in its bearing lin the snath.However much leverage there is exerted by the blade upon the adjusting-plate, the bolt remains fast. To readjust the blade the bolt Fmust iirst be loosened and the teeth f f disengaged from the plate E.Then after the blade has been inclined as desired the bolt F is drawnagain to bring the teeth into another set of the depressions e'i e.

I claim- The adj Listing-plate E, pivoted, slotted, and having thedepressions c e", in combination with the clamping-bolt F, having one ormore teeth, f f, extended, as described, substantially as and for thepurpose set forth.
